  7. I N D I A N A U N I V E R S I T Y IU-DML系統架構

  8. DML Testbed System: 4-Layered Architecture • Repositories: metadata, audio, video, music score images, etc. • Access components: search, image retrieval, audio retrieval, etc. • User interface components: sound player, score viewer, search/browse tool, etc. • End-user applications: library search and retrieval, music theory instruction, oncourse

  9. Visual Reserve List

  11. Standards and best practices endorsed by the DLF • Metadata Encoding and Transmission Standard (METS) • The Open Archives Initiative • Standards for electronic resource management • Institute of Museums and Library Services (IMLS). Framework of Guidance for Building Good Digital Collections • Benchmarking digital reproductions of printed monographs and serials • The Liblicense model licensing agreement • TEI text encoding in libraries, Version 1 http://www.diglib.org/standards.htm

  14. 大綱 • 從Web 環境談起 • 從數位圖書館系統與服務談起 • 圖書館自動化系統的新發展

  15. OCLC的 Open WorldCat

  16. OCLC will use tools such as xISBN and FRBR models to organize WorldCat public views suitable for low precision access Open WorldCat Architecture WorldCat , Additional collections can be added to Worldcatlibraries domain Metadata Schemas and Vocabularies OCLC Developed Geo-locator services to matches users to extensive FirstSearch WorldCat institution and user profiles Profiles and Relationships OCLC Uses Host of Authentication and Authorization tools to progressively match content to rights Content Owner Access OCLC Organizes WorldCat content in model suitable for harvesting, anticipate unique aspects of various portals Aggregators Distribution, Search, Display Google, Yahoo and Book Vendors Portals Organization and Presentation

  17. XML 自動化系統

  18. Parent Organization Accounting/Personnel/Student Registration Systems User Services Personal Corporate External Resources Integrated Search Interface/ Customized Resource Views Custom Access/Privileges/ Authentical Acquisitions Licensing Records Authorities Works Users “Cataloging” Vendors Interlibrary Loan Circulation Transactions Transactions Transactions Serials Control Usage Statistics Policies Routings Patterns Physical Claims Digital Bindery Holdings Items Other Archives, Libraries, Museums Publishers, Vendors

  19. Concept abstract collective specific “notional” Instantiation (specific authorities derived from selected collective Concepts) Language Organization Event Time String “substantive” instantiation (derived generic authorities and/or specific instances) authority Place Instance both authority Being Instance both authority Object Instance both authority Work Instance both Version? Version? Version(optional) Version(optional) Legend: Bold Boxes=Principal Elements Italics=selected attributes Solid Boxes=selected elements Dotted Boxes= implicit structure/ detail Holdings Item

  20. HKCAN XML platform Records in Communication MARC format with EACC encoding Program to convert records from Communication MARC format to XML format Records in XML format with EACC encoding Program to convert the records from CCCII encoding to UTF-8 encoding Records in XML format with UTF-8 encoding Import the records to a relational database for index search HKCAN XML full text search server (Tamino) for full text search, records display & download HKCAN index search server (SQL anywhere 8.0) Retrieve the full record from HKCAN XML server MARC Web interface Index search Full text search

  21. Record conversion From MARC record with EACC encoding

  22. Record conversion (cont’d) To XML record with EACC encoding

  23. Record conversion (cont’d) To XML record with UTF-8 encoding

  24. FRBR的應用

  25. IFLA’s FRBR Model • ER-Model, three groups of entities • Four operations on entities: search, identify, select, obtain is realized through Work Person Corporate Body Expression is embodied in Translation is exemplified by Manifestation Item Adaptation Whole/Part Christian Mönch, Trond Aalberg, „ Automatic Conversion from MARC to FRBR”

  26. 自動建立 FRBR Instances • Extract manifestations and items from records • Identify and split aggregative records • Cluster record set to identify works • Cluster work sets to identify expressions • Create entities from the clusters Manifestation Records Item Splitting SRecords Work Clustering SRecords Work 1 SRecords Work 2 Work Expression Clustering is realized through SRecords Expression 1 SRecords Expression 2 Expression Christian Mönch, Trond Aalberg, „ Automatic Conversion from MARC to FRBR”

  27. Obstacles to the Automatic Creation FRBR Model Instances • Inconsistency of data in catalogs: • Identical information is represented differently in different records (attributes, syntaxes) • Erroneous data • Incompleteness of data in catalogs: • Information necessary for clustering has not been captured in the records Christian Mönch, Trond Aalberg, „ Automatic Conversion from MARC to FRBR”

  28. Obstacles to the Automatic Creation FRBR Model Instances • Inconsistency of data in catalogs: • Identical information is represented differently in different records (attributes, syntaxes) • Erroneous data Might be resolved automaticaly,for example, through authority files • Incompleteness of data in catalogs: • Information necessary for clustering has not been captured in the records Christian Mönch, Trond Aalberg, „ Automatic Conversion from MARC to FRBR”

  29. Obstacles to the Automatic Creation FRBR Model Instances • Inconsistency of data in catalogs: • Identical information is represented differently in different records (attributes, syntaxes) • Erroneous data • Incompleteness of data in catalogs: • Information necessary for clustering has not been captured in the records Requires additional informationlinked to individual records Christian Mönch, Trond Aalberg, „ Automatic Conversion from MARC to FRBR”

  30. 博碩士論文以FRBR呈現 • 作品關連 • 師承關連 • 引文關連 • 後續研究關連(successor) • 姐妹研究關連(has a complement)

  31. 電子資源整合檢索

  32. SFX server 提供各種可能的資源 Source送出OpenURL target提供資源

  33. The Technology Landscape major trends • An increasingly interconnected environment • Network services and architecture • New standards • Universal access to information

  34. An increasingly interconnected environment • 為何環境有越來越多的連結需求 • 數位時代圖書館需有更多的系統支援 • 聯盟的成立及其他的合作計畫迫使系統需連結 • 需與非圖書館單位連結，如校園入口網站或教學系統 • 跨應用系統的單一授權服務

  35. An increasingly interconnected environment • System support • Library management system • Digital object management system • Portal or metasearch system • Resolver/Linker • ILL/resource sharing system • Growth of formalized sharing • Interconnecting and interoperability

  36. The Technology Landscape major trends • An increasingly interconnected environment • Network services and architecture • New standards • Universal access to information

  37. Network services and architecture • Presentation services • Application • Content services • Common services

  38. The Technology Landscape major trends • An increasingly interconnected environment • Network services and architecture • New standards • Universal access to information

  39. New standards • Repository and content standards • OAIS • Preservation • Content packaging • Content exchange • Metadata • Application • Cross searching: Z39.50 • Harvesting: OAI • Resolution: OpenURL • Niche library transaction application: NCIP and ILL

  40. The Technology Landscape major trends • An increasingly interconnected environment • Network services and architecture • New standards • Universal access to information

  41. Universal access to information • Semantic web • Web services • Grid computing • Wireless technology

  42. 圖書館資訊系統要跟什麼整合 • 新的網路環境 • 數位出版環境 • 數位典藏環境 • 數位學習環境

  43. 以圖書館自動化系統包括數位圖書館系統，或以數位圖書館系統包括原圖書館自動化系統功能以圖書館自動化系統包括數位圖書館系統，或以數位圖書館系統包括原圖書館自動化系統功能
